I get this error.

我收到这个错误。

error: warning: incompatible implicit declaration of built-in function ‘memcpy' [enabled by default]

This is the code:

这是代码:

int arr[ 12] = {1,0,0,0,0,0,0,0,0,0,9370, 0};
void *a = &arr;
memcpy(machine->mem, a,12*4);

You likely forgot to include <string.h>.

您可能忘记包含<string.h>.

Add #include <string.h>to the top of your file.

添加#include <string.h>到文件的顶部。
